Can we have a behavior script to make the user 'select only one value' in the Multi-select field?

Hi Kiranped,

Yes, you can. The multi-select field will return an ArrayList of Strings when you call the getValue method on its FormField.

Then, you can check the size of the array:

def multiSelect = getFieldById(getFieldChanged())
def multiSelectValue = multiSelect.getValue() as ArrayList

if (multiSelectValue.size() > 1) {
    multiSelect.setError("Please select only 1 value")
} else {
    multiSelect.clearError()
}

Hope this helps
